Recommended Extended Ball Mount or Hitch Extender for Towing Boat Trailer
Products Featured in This Question
Question:
Further looking, Why did you not recommend Reese Class III RP21141 or TK5007 for my Tahoe? The RP21141 description only says Long Shank, I assume long enough, also description does not indicate Stud on Ball Diameter

Helpful Expert Reply:
For your 2018 Tahoe and boat trailer needing a longer extension between them I recommend the Brophy Ball Mount for 2" Hitch - 3/4" Rise, 2" Drop - 13-1/4" Long - 10,000 lbs # BM20. Having a longer ball mount like this will not reduce the capacity of your hitch at all. This will give you a length of 13-1/4 inches from the center of the ball to the hitch pin hole.
For a compatible hitch ball the shank needs to be 1 inch diameter for this mount. I recommend the 2 inch ball # 40038 or 2-5/16 inch ball # C40007.

Thanks, (So Far) But the Tahoe is also significantly taller, and it required replacing my Ball Mount with one with a 4 Inch Drop. Answer this, I am towing with no problem, just cannot raise hatch. Why is the extension rated higher with load distribution equipment? I am thinking of just buying the HE06 Extension. I need 4 inches between Hitch Pin Holes, it is the shortest one you carry that I find and has 7 3/8 inches between centers. Big Thank You in advance!
